Introduction. The lungs are one of the most common sites of metastases from carcinomas and sarcomas. Secondary pulmonary tumors are typically multiple, oval in shape and located in the lung periphery. Cavitation of metastatic pulmonary nodules is extremely rare and most often occurs in primary squamous cell carcinomas of the head and neck and the cervix. Case Report. We report the case of a 62-year-old man presenting with dysphagia for solid foods and weight loss in the last two months. The patient had a history of long-term smoking and regular alcohol consumption. A barium meal showed irregular stricture in the proximal esophagus, highly suspicious of malignancy. Computed tomography of the neck and thorax showed tumor infiltration of the cervical and proximal part of the thoracic esophagus and multiple cavitary and solid pulmonary metastases. Conclusion. High-resolution computed tomography of the chest and radiological features such as a wall nodules, irregular internal contour of the cavity and spiculated edges allow precise characterization of cavitary metastatic lesions.

A 28-year-old patient was admitted to radiology department due to a painless left-sided extra scrotal lump and discomfort in the ipsilateral lower inguinal region. Scrotal ultrasound revealed an oval circumscribed soft tissue mass, located in the proximity of the distal part of spermatic cord, without visible flow at Color Doppler. Scrotal MRI depicted T2 hyperintense, T1 hypo-to isointense oval mass with diffusion restriction and no fat suppression, surrounded by T1/T2 hypointense rim, located close to the spermatic cord. Additionally, MRI revealed coma-shaped T1 iso-/T2 hypointense related to the testicle formation. Following the intravenous administration of gadolinium-based contrast agent, both previously described structures enhanced. Taking into account that malignancy could be the potential complication of polyorchidism our patient was operated and histopathology confirmed supernumerary testicle with cribriform epididymal hyperplasia.

Introduction. Zinner syndrome is a rare congenital malformation characterized by ipsilateral renal agenesis or hypoplasia, seminal vesicle cysts, and ejaculatory duct obstruction. Patients are usually asymptomatic or develop unspecific symptoms. Case Report. We present a case of a 22-year-old male patient who presented with painless terminal hematuria. The patient denied trauma or other urinary tract symptoms. Magnetic resonance imaging of the abdomen and pelvis revealed a right renal hypoplasia, a tortuous dilated right ureter draining into polycystic right seminal vesicle, and a dilated ejaculatory duct. Conclusion. The size of the seminal vesicle cyst and symptoms affect the treatment. Asymptomatic cysts may be treated conservatively, while cysts that cause symptoms are often an indication for surgical treatment, due to the possibility of infertility caused by the obstruction of the ejaculatory canal. Magnetic resonance imaging has high-resolution properties providing excellent presentation of anatomical relationships and pathology which is extremely important in case of the need for surgical treatment.

Introduction. The aorta is a major blood vessel that supplies all segments of the human body. Acute aortic syndrome is a term that implies a life-threatening aortic disease. Due to the speed of examination and widespread availability, computed tomography angiography is a front-line diagnostic modality for emergencies and diseases of the abdominal aorta. The aim of this study was to provide a wide range of potentially life-threatening abnormalities of the abdominal aorta in daily clinical and radiological practice through a series of computed tomography angiography images and three-dimensional virtual reconstruction. Abdominal aortic aneurysm is defined as a 50% increase in diameter more than the normal arterial diameter. One of the most important complications of an aneurysm is a rupture that can be acute or chronic, presenting with various clinical manifestations. Aortic dissections are caused by abnormality of the tunica media layer, forming an intimal-medial flap and two types of lumen. A penetrating aortic ulcer may erode through the internal elastic lamina of the aortic wall and allow formation of hematoma within the tunica media. Occlusive disease of the abdominal aorta may refer to the late stage of chronic aortoiliac occlusive disease, whereas the acute and/or subacute form occurs due to sudden thrombosis or occlusion. Conclusion. The recognition of specific radiological signs of abdominal aortic disease using computed tomography angiography contributes to optimal treatment of patients and reduces mortality.
